Trans-X is to be used to clear out any varnish and gum in the transmission. After its clear, you ought not need to use it again for a long time. Ideally, you want to do this prior to the fluid change by siphoning out a quart of ATF, and adding a quart of Trans-X to the mix. It shouldn't stay in any longer than 1000 mi. After the 1k mi, drain the pan, torque convertor, and replace the filter. Refill with fresh fluid and a new filter as you'd normally do, NO Trans-x added this time, and you ought to be good to go, that is if you had a problem that Trans-X could fix in the first place. If the Trans-X didn't work, it's going to be something only mechanical work can fix.
